Design for Team Pending

Our design combines a moving chassis with workable arm in order to move the Ping Pong Balls in a manner that is not dependent on a perfect circumstance. The machine has a arm with a wedge that lowers into the tank and flips out to form a platform for lifting the PPBs. The arm moves up and down on a rack and pinion moved by a planetary gearbox and is constrained by sets of wheels to limit the motion to one degree of freedom. The wedge is flipped out by a winch attached to another planetary gearbox. The machine can then move over to the wall and lift the PPBs over and onto the opponent's side. The chassis movement is provided by the Tamiya double gearbox which is connected to a set of 4-wheel treads. The treads increase the friction between the table and the machine, which will help stop the opponents from moving and forcing our machine.
